Abstract: | Liquid junction solar cells, made from electrochemically doped p-type trans-polyacetylene in contact with aqueous solution of methyl viologen, were constructed. The turn-on potential was found to be +1.0 V versus SCE. The spectral response showed low quantum efficiency (?10?4) for photoinduced charge separation with a threshold around 1.5 eV. The electroreflectance showed the presence of two transitions at 1.45 and at 1.6 eV. A tentative assignment of these transitions is proposed. |
